naledsupportingWheels 11 and 12.'V A horizontal frame 13 is connected toand supportedi'rom the axle, and to the front portion of vthis frameforward of the right wheehshafts 11i are rigidly/connected. A tiibular'member l'siirronnds and is'rigidly connected to the shaft 10, and formspart of the vframe 13, and the Wheelsll and 12 are loosely journaled ontheshaft parts at the oppositeend portions ofthe tubular member. `An arm16 secured to the tubular' member 15 extends upwardly Aand rearwardlytherefrom, andV is provided .with a seat 17, so `that the Weight of thedriver willA almostc ounterbalancethe forward portion the machine. `Twoarms 18 which are rigicly connected to the opposite end portionstrib-:iler ineinherA 15, andgarcect for` wardly therefrom, are pivotallyconnected to the opposite side'portions of a container oi hopper 19 bypivot shafts 20. in 'arm 21 rigidly connectedto the tubular vmember 15at one end portion,` and extending upwardly therefrom, is pivotallyconnected at its upper end to a linlr 22, which in turn is pivotallyconnected at its lower end to a controlling lever The lever 23 carries aspring actuated dog 211 which engages the teeth of a segmental rack 25for holding the parts in adjusted poe sition. The arm 2l extends atright angles to the arms 18, and as they are all rigidly coniiectedtogether, Vtdieyv form in substance a `bell crank lever connectionbetween the link and the hopper.

The frame 18 is provided with a depending "braclret'ZG though which theshaft or axle l() extends, and said bracket is formed with a downwardextension 2G to which one end of a parallelograin link 27 is pivotallycon- Tho opposite end of t-his linlr 27 is pivotally connected to oneside portion ofthe hopper 19 below the pivot pin 20, and

forms, in conjunction with the arm 18 a par.

allelogram connection between the frame and the hopper, so that when thelever 23 is l pushed forwar illy,the hopper will be raised withoutchanging its angularity.

The right hand end portion of the shaft 10 has journaled thereon asprocket wheel 28 which is connected to and turns with the right handwheel 11. ASprocket wheels 29 and 30 are Valso mounted on the outer andinner end portions of the right hand pivot shaft 20, and a sprocketchain 31 connects the sprocket wheels 28 and 29 drivingly together.

A chain tightener 32 in the form of an idle pulley bears on the chain 31to take up slack. A shaft 33 journaled on the upper forward 'fportion ofthe hopperl) carries opposite spiders 84 to `which a Vseries of spacedtransveiselyV extending.briiishcs 'are connected, i

Y and are adapted 'to sweep .inwardly and over the forward odge 36 ofthe hopper.

sprocket .wheel 37 mounted on the brush shaft 33 has a .sprocket chainconnection 38, with vand is driven bythe sprocket wheel 30 on lthe shaft2O. An idler pulley 38 prevents slack in said chain 38.

, The brushes are formed of comparatively long bristles or othermaterial which will not injure the plants brushed. rlhe forward portionof the hopper 'is provided with transverse rods 39 against which theplantsl are V"pressed in brushing the upper side portions thereof. Theaxis of the brushis positioned in a vertical plane to the rear of thelower 4 forward edge of the hopper, so that the brush will press thelower sides of the plants against said edge and the transverse `rodsduring the brushing operation. As the machine is trav-V elingV 'duringthe brushing foperation, the f lower `side portions vof the plants willrub against the rods 39 and the aphides and other it will have to beemptied.

insects will be scraped from the lower surfaces of the plants and dropinto the hopper beneath the rods. brushes will brush the insects fromthe upperl surfaces of the plants into the hopper. The Y forward edge 36of the hopper is of rounded formation to prevent injury to the plants.The position of the brush and its rotation tends to brush the insectstowards the rear portion of the hopper, so that said hopper will hold alarge mass of the insects before The front land the forward' part of theupper portion of the hopper are open to permit the brusliniein# ber torotate therein, 'while the uppera'ear portion is covered by a` screenframe 39 to At the same time, the v f permit the upward flow of the airmoved by y the brush and prevent the insects being carried therewith. YSaid screen frame is adjustl ably connected tothe hopperk by bolts andthumb nuts 40 which extend through slotted portions a1 of the screenframe and hopper 19. As thus arranged, the screen frame may.

be adjusted so that its forward edge will just clear the ends of thebristles offthe brush,

or so that the brushes will brush against the edge to scrape or shakeolf Vthe insects there-` from and into the hopper.' The rear portion ofthe hopper is formed with ay discharge opening l2 closedfby a hingeddoor alield in closed position byalatch 4ta, and through which openingthe insects are discharged.

In use, it is only necessary to driveove'r,Y`

the field covered with the plants, and the movement of the vehicle willrotate the brush members and bendl the plants over the forward edge vofthe hopper and the transverse rods. The rotary movement of the brushmember and the` forward movement of rthe twenty. to forty degrees, andthe aphidesfwill be destroyed by the hoatengendered,`. andV the mass maybe dumped upon the jg'ground.`

F rom the foregoing description, it Will be seen that the aphis removingmachine is Vof for the purpose described.
